Dear All,
Thanks so much for all your thoughts into the single/triple rose
conundrum. It is obviously so hard to know just how this aspect changes
the tonal colours of lutes. It is also very difficult to test just how
this one aspect alters things given that every lute is different, even
if it is the same model from the same maker.
I will continue to do some intuitive and highly unscientific tests!
Best wishes,
Benjamin

I fear there is a natural tendency to think of the rose as the hole
that "lets the sound out", but I think this is a case where
intuitive physics lets us down.A The size of the opening affects
the natural resonant frequency of the body, with a smaller opening
giving a lower frequency.
But I invite all you proper physicists out there to explain why!
A more complex issue, but one which is related in that it also
involves a mismatch between intuitive physics and the real thing:
many people seem to believe that the lute soundboard should be
flexible to "allow it to vibrate", and that the more flexible it is
the better the bass response.A In fact I think - please contradict
me if I'm wrong - that the frequencies which we are interested in
are far too high to be aided by a floppy soundboard, which is more
likely to have a damping effect.A As far as I can see, a relatively
rigid soundboard is going to produce a more sustained sound.A The
most important factor is the mass, which must be kept as small as
possible so it can be activated by a small input of energy - hence
the rather thin soundboards (supported by many bars to retain
sufficient rigidity) required by lutes.

A A Dear All,

have

A A I have had many lutes/theorboes with both single and triple

make more

more
